One app. Every frontier AI. Zero knowledge of who you are. ChtSafe brings GPT-5.4, Claude 4.6, Gemini 3.1 Pro, Grok, DeepSeek, Perplexity, and leading open-source models into a single encrypted workspace — and lets them work together on your hardest problems. WHY ONE MODEL WHEN YOU CAN HAVE THEM ALL Composer runs your prompt across several frontier models at once and synthesizes the strongest answer. Want receipts? Every raw output is right there, side by side. PRIVACY THAT ACTUALLY MEANS SOMETHING The ShinrAI Encryption Engine anonymizes and encrypts every prompt with a zero-knowledge design. Neither ChtSafe nor the model vendors can see who you are. Ideal for sensitive questions, trade secrets, and conversations that leave no trace. FILES WITHOUT THE WORRY Drop in PDFs, Excel, Word, and images. Everything is processed on a private GPU cluster — only anonymized vector embeddings ever leave. ANSWERS YOU CAN CHECK Research agents cross-reference responses against live sources, including web search and Perplexity. Grounded information instead of confident guessing. A FULL MEDIA SUITE Generate images, music (Google Lyria), video, and audio — including the Nano Banana 2 image model. Right in the chat, editable with follow-up prompts, and fully encrypted. COMPLETELY REBUILT IN v2.7.3 • Streaming chat with visible thinking and tool steps • @-mention knowledgebase files and connected folders (Nextcloud, OneDrive, SharePoint) • Switch seamlessly between desktop and phone — your chat just keeps going • Automatic recovery from network drops • New desktop apps for macOS, Windows, and Linux (beta) ONE SUBSCRIPTION INSTEAD OF THREE Replace ChatGPT Plus, Claude Pro, and Gemini Advanced with a single plan. Choose Unlimited monthly or yearly, or pay as you go with Sparks that never expire. ChtSafe is built for privacy-conscious professionals, entrepreneurs, and researchers who want frontier AI without handing over their data. Top-tier models and real privacy — you no longer have to choose. Download ChtSafe today.
